Abstract

Abstract Ion-plated metallic films in contrast with films applied by other deposition techniques offer lower friction coefficients and longer endurance lives and exhibit a gradual increase in the friction coefficient after the film has been worn off. The friction coefficients of metallic films are affected by the degree of adherence, the thickness and the nucleation and growth characteristics. The effective film thickness for the minimum friction coefficient was established for gold and lead films. The nucleation and growth characteristics during ion plating lead to a fine continuous crystalline structure, which contributes to a lower friction coefficient.
